Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: transmitting a video communication through a network; detecting, via a processor, a video quality degradation of the video communication based on network packet-level measurements and baseline degradation values; prioritizing a plurality of categories of quality degradations to yield a prioritization, wherein each category in the plurality of categories of quality degradation comprises one of jitter, duplication, block artifacts, snow, static, delay, or loss of audio; identifying, from the plurality of categories of quality degradation, a category of video quality degradation that corresponds to the video quality degradation; based on the prioritization, prioritizing a plurality of countermeasures corresponding to the plurality of video quality degradations to yield a table that matches the plurality of countermeasures specifying respective corrective video parameters with the plurality of categories of quality degradations; selecting, from the table, a countermeasure to correct quality degradations of the category of video quality degradation; and in response to the video quality degradation, implementing the countermeasure in real time.
2. The method of claim 1 , wherein detecting the video quality degradation is further based on a quality of service being measured over a video communication path through the network.
3. The method of claim 1 , wherein the video quality degradation is determined from at least one of a bit error rate, a network packet loss, or a burst loss density.
4. The method of claim 1 , further comprising: evaluating multiple communication paths through the network; and transmitting the video communication over one or more of the multiple communication paths.
5. The method of claim 1 , wherein the plurality of countermeasures comprises at least one of a change in bit-rate or a modification to inter-frame compression encoding parameters.
6. The method of claim 5 , wherein the network packet level measurement is one of processed or unprocessed video quality measurements.
7. A system comprising: a processor; and a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising: transmitting a video communication through a network; detecting a video quality degradation of the video communication based on network packet-level measurements and baseline degradation values; prioritizing a plurality of categories of quality degradations to yield a prioritization, wherein each category in the plurality of categories of quality degradation comprises one of jitter, duplication, block artifacts, snow, static, delay, or loss of audio; identifying, from the plurality of categories of quality degradation, a category of video quality degradation that corresponds to the video quality degradation; based on the prioritization, prioritizing a plurality of countermeasures corresponding to the plurality of video quality degradations to yield a table that matches the plurality of countermeasures specifying respective corrective video parameters with the plurality of categories of quality degradations; selecting, from the table, a countermeasure to correct quality degradations of the category of video quality degradation; and in response to the video quality degradation, implementing the countermeasure in real time.
8. The system of claim 7 , the computer-readable storage medium storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising: based on at least one of video path measurements or desired video quality, establishing the baseline video quality values; and creating the table.
9. The system of claim 7 , wherein detecting the video quality degradation is further based on a quality of service being measured over a video communication path through the network.
10. The system of claim 7 , wherein the plurality of countermeasures comprises at least one of a change in bit-rate or a modification to inter-frame compression encoding parameters.
11. The system of claim 7 , wherein the computer-readable storage medium stores additional instructions which, when executed by the processor, cause the processor to perform further operations comprising: evaluating multiple communication paths through the network; and transmitting the video communication over one or more of the multiple communication paths.
12. The system of claim 11 , wherein the network packet-level measurements comprise at least one of bit error rate, network packet loss, or burst loss density.
13. A computer-readable storage device storing instructions which, when executed by a processor, cause the processor to perform operations comprising: transmitting a video communication through a network; detecting a video quality degradation of the video communication based on network packet-level measurements and baseline degradation values; prioritizing a plurality of categories of quality degradations to yield a prioritization, wherein each category in the plurality of categories of quality degradation comprises one of jitter, duplication, block artifacts, snow, static, delay, or loss of audio; identifying, from the plurality of categories of quality degradation, a category of video quality degradation that corresponds to the video quality degradation; based on the prioritization, prioritizing a plurality of countermeasures corresponding to the plurality of video quality degradations to yield a table that matches the plurality of countermeasures specifying respective corrective video parameters with the plurality of categories of quality degradations; selecting, from the table, a countermeasure to correct quality degradations of the category of video quality degradation; and in response to the video quality degradation, implementing the countermeasure in real time.
14. The computer-readable storage device of claim 13 , wherein detecting the video quality degradation is further based on a quality of service being measured over a video communication path through the network.
15. The computer-readable storage device of claim 13 , wherein each countermeasure within the plurality of countermeasures corresponds to a specific level of video quality degradation detected.
16. The computer-readable storage device of claim 13 , wherein at least one countermeasure within the plurality of countermeasures measures modifies inter-frame compression.
17. The computer-readable storage device of claim 13 , wherein the network packet-level measurements comprise at least one of bit error rate, network packet loss, or burst loss density.
18. The computer-readable storage device of claim 13 , wherein the plurality of countermeasures comprises at least one of a change in bit-rate or a modification to inter-frame compression encoding parameters.
